Specification of Letters Patent.

1912. Serial No. 699,202.

To all who: it may concern:

Be it known that I. An'rirnn Barns, a subject of the King of England,residing at Leicester, Leicestershire, England, have in vented certainImprovements in Lasting- Machines, of which the following description,in connection with the accompanying drawings, is a specification, likereference characters on, the drawings indicating like parts in theseveral figures.

This invention relates to lasting machines, and more particularly tocertain improvements in lasting machines of the type dis- 58 lf4l4c,dated June 15, .1897. In the machine of said Letters Patent the upper isworked into lasted position by devices not ing upon successive portionsof the stock by repeated operations, such devices comprising pincerswhich are actuated to grip and pull the upper, and to lay it over uponthe innersole, and a wiper which follows the movements of the pincer-sand wipes or presses the overlaid upper material smoothly upon the solo.The upper is secured in lasted position by tacks one of which isdeposited in an. aperture in the wiper by suitable devices prior to eachadvance movement of the wiper over the shoe, and at the completion ofsuch movement the tack is driven through the lasted portion of the upperby a suitable driver. Machines of the type referred to are also providedwith mechanism to impart to the pincers lateral movements, and axialturning movements, to plait the upper at those portions of the shoewhere excessive fullness of the stock calls for such operation. the saidmechanism being under the operators control through devices which enablehim to vary the direction and extent of, as well as to initiate, orentirely suspend the plaiting movements at will.

A very important feature of the present invention consists in improvedmechanism for wiping the upper into lasted position comprising a wiperwhich is so constructed and arranged for operation as to move in aninclined path relatively to the edge of the shoe.

in the herein described embodiment of the invention the wiper comprisestwo members that are arranged for simultaneous movement toward and fromthe shoe. in a direction which may be normal to a curved edge of a shoe,along convergent paths that are inclined to the median line of themachine, so as to wipe the upper inwardly from the edge of the sole, andat the same time in opposite directions along or subslmitially parallelwith said edge. The wiper members are preferably crossed, as shown, andare pivoted at an intermediate point to their carrier, and have theirrear portions provided with guiding slots which are entered by a pin orprojection rigid with the frame of the machine. \Vhen the carrier movesinwardly toward the shoe and advances the wiper members over the edge ofthe sole the movement of the pin or proection along the guiding slotscauses the wipers to approach each other in the manner of a pair ofshears, and when the carrier moves away from the shoe a separatingmovement of the wipers is elfectecl by the same means.

Other features of the invention, including important details ofconstruction and combinations of parts, will be hereinafter moreparticularly described and claimed.

This application is a division of my Patent No. 1,029,841), granted June18. 1912, in which the generic claims are made covering 'lnroadly theconstruction herein illustrated.

In the drawings, Figure l is a perspeolive view of the principaloperative parts of a lasting machine with an embodiment of the presentinvention applied thereto, the supporting pedestal and frame beingomitted; Fig. 2 is an exploded view, show mg in perspective the wiperand its actuating devices. Fig. 3 is a plan view of the. wiper.

The main shaft l. of the machine which turns in suitable hearings in theframe, carries a cam block 2 which provided with a cam groove or way toreceive a roll on a slide t which is connected at its upper end to arocking lever This lever is ful- (u-uincd at (i, and is connected at itsforward end to the pincer bar 8, which is formed as a. sleeve andcarries at its lower end the jaw 10. The other pincer jaw 12 isconnected to a rod let that extends upwardly tl'u'ougli the sleeve 8 andis engaged at its upper end by a spring-pressed plunger 16 in a lever18. The lever 18 is 'lulcrunied at 20 in the lever 5 and carries on itsrear arm 21 a roll that rests upon an edge cam 22. The block having theedge cam 22 has also a cam groove in its front face to receive a roll ona lever 25, which is fulcrumed on a rod 26 and at its outer end carriesa segmental. rack whose teeth engage a pinion 28 on a sleeve shaft 30.This shaft is connected to a rocker 32 which carries a block 34connected by the rod 35 with a cross head 36 by means of which thepincers are caused to move or swing laterally. A link 37 con nects thecross head 36 r with a lever 39 which is fulcrumed through an adjustableblock to a pin 41 supported from the frame of the machine. The upper endof the lever 39 is connected through a rod 43 with. a rack which mesheswith a pinion fast on the upper part of the pincer bar 8, whereby toeffect the axial turning movements of the pincers simultaneously withthe lateral movements of the pincers informing the plaits or folds, saidparts being fully shown and described in Letters Patent No. 584,744heretofore referred to. The cross head36 is sup portedin a yoke 38 onthe front end of a slide rod 40 which carries a roll that is:

engaged by the rear face of the cam 22. A spring. 42, acting through alever 44, holds the rod forward with the roll against the cam. Avertically reciprocating rod which is guided in a boss on a bracketsupported from the frame of the machine is pivotally connected at oneend with an arm of. a bell-crank lever 46, said rod having the usualoperating mechanism including a knee lever as shown. Thebell-crank lever46 is fulcrumed at to the main frame, and is shown as having one armformed as yoke 62 which embraces a collar 64 connected through aninclined slot and pin, or the .like, with a shaft 55 located within thesleeve shaft 30. The connection between the collar and the shaft 55 issuch that a movement of the collar endwise on the sleeve serves to turnthe shaft through a small.

angle. The shaft 55 is connected at its, front tion and extent of suchmovements.

The mechanism described above for lowering and raising the pincers,closing them,

and swinging forwardly and backwardly, and for effecting their plaitingmovements are fully described in the aforesaid Letters Patent 'No.584,744, and of themselves form no part of the present invention. In theoperation of these parts it is deemed suflicient to explain that thepincers with the jaws open are lowered bythe cam 2 into position toseize the upper, closed by the cam 22, then uplifted by a furthermovement of the cam 2, and then moved forwardly over the shoe bottom bythe spring 42. lVhenthe knee lever is set to adjust the block in aneccentric position in the rocker 32 the pincers receive also lateral andtwisting movements for plaiting the,

upper, the plaits being laid inclined in either direction from themedian line of the shoe at the toe, or at the heel, according to theposition into which the block 34 is moved by the knee lever. A rockinglever 66 is fulcrumed at 68 to a bracket projecting from a rigid part ofthe frame 3. The upper end of the lever 66 carries a roll which operatesin a cam groove formed in a cam block 70, which is fast on'the drivingshaft 1. The lower end of the lever 66 is connected with a slide bar 7 2which is suitably guided for horizontal movementin the machine frame andat its forward end carries a wiper to cooperate with the pincers inworking the upper into lasted position. In prior machines of this type,similar parts to those just described are shown, the wiper being rigidlycarried at the forward end of the slide bar, and being provided with anaperture to receive a tack.

In operation, the slide bar isrecipr'ocated to carry the wiper back andforth by the cam 70, and when it reaches a suitable position initsrearward movement a tack is defrom the edge of the shoe, but is movablysupported by the bar and operated in such manner that it has othermovements imparted to it, whereby it may wipe or press the upper indirections which will conform to the inclination of the folds or plaitsin the upper at the toe or at the heel of the shoe, as will be now moreparticularly described. The reciprocatory slide bar 7 2 has secured toits forward end by screws 76 a wiper carrier or support. 74 Fig. 2. Thecarrier 74 is shown as having a tacloreceiving aperture 78, and at asuitable point preferably to the rear of its forward extremity isapertured to receive a stud or screw 80 from which the parts of thewiper are pivotally supported at a point between their ends. The wipermembers are shown as having notches in their inclosed position, and istherefore in longitudinal alinement with the carrier.

As herein shown the wiper comprises two independent, movable sections,which are so constructed and arranged for operation that when theyoccupy a retracted position said sections are extended laterally fromthe center line of the wiper-carrying slide bar, or actuator, and havetheir acting edges and faces inclined relatively to said line, but assaid sections are advanced toward the shoe they are caused to approacheach other and wipe the stock laterally along convergent paths that meetat said center line. In this construction, the wiper sections comprisethe two bars 116 and 117 which are crossed similar to a pair of shears,and supported by the single pivot 80 which may be sustained from acarrier such as that indicated by the numeral 74;, in Fig. 2, to bereciprocated horizontally by the slide bar, or by any suitable memberhaving movement to carry the 'wipers toward and from the shoe. To therear of the pivotal connection 80 the wiper bars are provided with slots120, which re ceive a pin or roll 122 which is fixed rigidly to a partof the machine frame. \Vhcn the slide bar is advanced in the operationof the machine the slots 120 will slide over the pin or roll 122 andcause the wiper sections to close together as they are advanced, theconstruction, as well as the operation of these parts, correspomlingsomewhat to those of a pair of shears. The carrier or support for thewiper sections may be adj ustably secured to the slide bar, and in thatcase the pin or roll 122 will be adjustably fastened to the stationarypart of the frame which supports it.

While the parts of the wiper are deflected outwardly from thelongitudinal central line of the machine when retracted, it is necessary that at its most advanced position the wiper should present itstack-receiving aperture in alinement with the aperture 78 in the carrierand also in alinement with the driver 79 in order that the tack may thenbe driven into the stock. To this end the slots 120 are inclinedrelatively to the center line of the machine and extend inwardly andtoward the rear. The inclination of these slots to each other willtherefore be greatest when a the wiper is in its extreme rear position,and

as the. two-part wiper advances toward the shoe the lateral deflectionor inclination of its parts will decrease gradually as the roll 122iLPPI'OiU'fllQS the outer end of the slots 120. Said roll being in linewith the central line of the machine, the wiper will, as a whole, occupya central position where its aperture S-il is in alinement with theaperture 78 and also with the driver 79.

It is thought that the operation of the several features abovedescribed, as well as their advantages, will be apparent without furtherdescription. The wiper, as in former machines of this same generalcharacter, is so actuated in time relation to the operation of thepincers that when the pincers have seized the upper, uplifted tostretchthe leather, and moved inwardly to lay the upper upon theinner-sole, the wiper is advanced and wipes smoothly the overlaid stockinto its final lasted position and in accordance with this invention thewiping movements take place along convergent paths directed toward thedriver which descends and forces into the stock the tack which vascarried forward by the wiper. It is to be understood, however, thatwhile the herein described wiper is useful in the operation of formingplaits or folds in connection with pincers whose movements are such asthose described herein, the invention is not in any sense limited to theuse of such wiper with pincer mechanism that produces plaitingmovements, nor in fact with any pincer member, for it will be obvious tothose skilled in the art that wipers having such capacities for movementwill have many advantages in lasting machines that work the upper intolasted position without the use of pincers.
